LUMBER GAUGE.

Application led May 31, 1922. Serial No. 564,766,

provision of a comparatively inexpensive but4 accurate measuringinstrument, which may be manipulated with facilityT by the lumber graderin his work of measuring, grading and marking the lumber as itcomes'from the saw mills, as well as in gradingthe material in piles.

With these ends in view the invention con will be hereinafter more fullypointed out' and claimed.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention where,- in the parts arecombined and arranged according to the best mode I have thus far devisedfor the practical application of the principles of my invention. j

Figure 1 is a perspective view of the yinstrument in position for use asa marker.

Figure 2 is a perspective view, enlarged, showing the instrument readyfor gaging or measuring lumber, and also capable of use as a marker.

Figure 3 is a detail sectional view atthe marking end of the instrument,showing the manner of securing the chalk, crayon, or other sharpenedmarker to the instrument.

'Figure 4 is a perspective view of the handle portion of the instrument,detached.

In the preferred form of the invention as illustrated in the drawings,lthe gauge-bar 1 is of suitable wood and convenient size for .itsrequired functions, and fashioned with a body portion 2 integraltherewith, but cut to different shape with a flat face 3, as shown inFigure 2.' v'Ihe body of the' measuring gauge is vse1nicircular in crosssection, and preferably tapers in both directions toward front and rearfrom the abrupt shoulder 4, which is 'squared with the flat face of thebody of the gauge. n j

At the junction of the bar and `body a metal wear plate 5 is inset intothe wood, said plate being somewhat of an L-shape, and? forming an,angular scale plate with graduations'ininches and fractions thereof,

extending along one edge of the iiattened body 2. The same scale ininches, is also continued along kthe edge of the flattened gauge body,by the utilization of groups of notches 6y for marking off two-inchspaces, thus providing 'a scale twelve inches longl extending `from the`shoulder 4 to the end of the gauge body. 'The notches 6 are ar-`rangedin groups 0f three, of which the intermediate notch indicates astandard measurement and the two outervnotches indicate van, undersizeand an oversize respectively by a pencil or marker 7, sharpened ofcourse,

and made up of crayon, chalk, or other suitable marking material. Themarking point is renewable and adjustable, and is retained in its socket8 inthe end of the gauge bar by means of a metal cap or thimble 9 having angopening 10 for the pencil or challn The cap is preferablyresilient and tapered in order that itmay be shoved over the socket endof the bar and frictionally hold the pencil point kor chalk in positionfor use.

The detachable handle 11 of the instrument is of `convenient formandshape, and fashioned with anundercut portion 12 having smooth or fiatface 13 complementary to the flat face 3 of the gaugeQbar. At one endthe handle is provided with a sharpened pin `or spike 14 adapted, to beinserted in the hole 15 in the shoulder 4 of the gauge bar, and a .pin17 projecting from the yflat face of the `handle Vis adapted to `projectinto a socket or hole 18 in the flat face of the gauge bar.

In Figure 1 it will be seen that the complementary members 2 and 12 areadapted to overlap with the end 16 and shoulder 4 in engagement, and theshoulder 19 and end 20 are also adapted to engage. r'Ihus with the guide`pins inl their sockets holdingthe separable members against bothlongitudinal to a pencil.

and lateral movement, a rubber metal or ring Q1 may be slipped over oneend of the instrument to retain the parts in position. By slipping' vthering back to dotted position in Figurel the parts may readily beseparated, and the gauge bar, as in Figure 2, is then ready formeasurements. By hooking` the shouldered bar (as at 4) over the edge ofa plank or board, its dimensions may readily be ascertained byconsulting the scalejthen if desired the pointed marker may be withdrawnand the lumber marked; or the pointed marker may remain in its holderand the gaugebar used in manner similar It will also be quite evidentthat the instrument as shown in Figure l may be used in manner similarto av` pencil for making` required markings in gradingT the material. asNo. 2 common,common, cull, &c. When using;- the marker as in Figure lthe grader is enabled to stand erect and mark the characters ordesignations on the boards as they are taken from a pile, thusproviding' a convenient device for the purpose, and rendering' the Workof the grader less arduous.

Having thus fully described my invention, what l claim as new and desireto secure by Letters Patent is l. A. gauge bar having a cut out portionforming a flat face and a squared shoulder. an angular plate having aScale thereon and attached to said bar at the junction of the flat faceyand shoulder, and spaced groups of notches in the bar 'forming acontinuation of said scale. v l y 2. The combination' in a lumber gaugeof a bar having a shoulder and cutout portion forming` a flat face, ascale including` spaced notches along the edge of said face, adetachable handle` portion forming' a shield for said scale and providedwith a complementary shoulder and flat face, complementary pins andsockets on said bar and handle portion, and a resilient retaining ringfor said latter members. j v In testimony whereof I alix my signature.

CARL HILMERSON.
